I Have A 2004 Dodge Ram:how Do I Connect An Amp Useing My Factory Radio . I've Bought A Converter Rca Line.were Do I Connect It At ...splice Into The Rear Speakers Or Radio ...if Its The Radio Which Wires?

The only thing you need to connect to the radio is the amp turn on wire and the rca cables. The turn on wire connects to the power wire for the radio so when the radio turns on so does the amp. And the wires on the converter should go with the colored wires on the back of the radio.
